ALEXANDER B. TODD, OF PHILADELPHIA, PENNSYLVANIA.

BRAKE-.SHOE.

SPECIFICATION forming part of Letters Patent No. 283,438, dated August 21, 1883,

Application filed June (I, 1883.

1'0 all whom; it may concern:

Be it known that I, ALEXANDER B. TODD,

of West Philadelphia, county of Philadelphia,

and State of Pennsylvania, have invented new 5 and useful Improvements-in Brake-Shoes; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention consists, mainly, in providing a brake-shoe, of any proper construction, upon its outer edge, with alight-angled flange adapted to overhang the outer edge of the wheel, as will be fully described hereinafter.

Inthe drawings, Figure 1 represents a side view of the brake-shoe of a driver-wheel to which my invention has been applied; Figs. 2 and 3, edge views of the same; and Fig. 4 a sectional View, showing a worn wheel.

To enable others skilled in the art to make my improved brake-shoe, I will proceed to describe fully the construction of the same.

7 3o which thebrake-shoe on each side of the engine are united together.

7 By means of the described construction the brake-shoes are always retained in their prop- (No model.)

er position relatively to the wheel, and hence thetendency of the sa ne,wh en without a flange, to lie in the hollow of a worn wheel and increase the wear is avoided. By means of this construction, also, the tendency of the shoe is to wear off the outer projection, 00, Fig. 4, resulting from the wear of the wheel, and restore the same to its normal condition.

The shoe is shown applied to the driver-wheel of an engine, but it may be applied to any wheel.

I am aware that it is not new to apply a flange to a brake-shoe in such manner as to overhang the inner edge of the wheel. Such-a construction does not accomplish the end desired by me.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A brake shoe having a right-angled flange adapted to overhang the outer edge of the wheel, as and for the purpose set forth.

2. In combination with a brake-shoe having a right-angled flange adapted to overhang the outer edge of the wheel, the stretcher-rods G G, as ahd for the purpose described.

This specification signed and witnessed this. 60 4th day of June, 1883.
